In my prior patent, No. 1,934,290, entitled Awning type window, issued November 2, 1933, I have described a window comprising a. plurality of sashes mounted for swinging movement in one frame and having means connecting the sashes whereby all or them may be opened and closed l by manipulafion of but one, and having means for rendering the connection between the sashes ineifective whereby one sash could be opened or closed independently of the others. In this prior patent the several sashes are described. as being connected together by means of travel bars and a. shoe which co-acts with the travel bars to chest connection or disconnection of the one sash relative tothe travel bars and the other 5251195. The shoe referred to 'is operated by manipulation of the one sash through which the other sashes are controlled so that auxiliary 0P- erating devices carried by the window-frame or elsewhere are entirely unnecessary. g It is to improvements in the structure of a shoe for this purpose and the mechanism associated therewith that the present invention is particularly directed. 4

It is the object of this invention to provide operating mechanism for multiple-sash windows whiehwillpermitanvoralioithe sashestobe controlled by opening and closing movementof a single sash, and which will include simple and positivelyoperating means capable of being actuated by movement or the controlling sash to place it in or out of its controlling relation with the other sashes.

It is a .Iurther object of my invention to provide mechanism through which a single control sash will, upon initial opening movement, impart opening movement to all sashes controlled by it and at the same time be free for closing movement independently of all sashes controlled by it, regardless of the angle to which the sashes have been opened.

It is also within the object of my invention to provide mechanism whereby the control sash will be operatively connected with the other sashes inFl 4; and

is made to the drawings and wherein further of its objects and'advantages are made apparent.

frame and sash illustrating the application of my 10 Fig. 5is a front elevation of the shoe illustrated l Figs. 6, 7, 8 and 9 are side elevations of the same shoe illustrating the positions that it will assume relative to the travel bar during operation of the sashes. I Referring more particularly tothe drawings, in Fig. 1 I illustrate one type'ot window to which my invention may be applied. The window here illustrated comprises a frame l0 and three superposed swinging sashes, illustrated at l I, shown in an open position but capable of being swung to a closed position wherein the three sashes oooperate to form a complete closure with the 30 frame II.

The sashes are substantially identical in construction, and are pivoted intermediate their top and bottom rails to the outer ends 01' links 12, the inner ends oi which links are pivoted as at l3 tothe frame Ill. Arms ll, secured to the upper outer edges or each sash, carry trunnions l5 which are slidable in vertically extending channel-shaped guldeways i6 provided in the Windowframe, as best illustrated in Fig. 2.

The sashes ii, being supported in the manner 40 above described, are free for swinging movement to and away from the frame and such swinging movement is accompanied by vertical sliding movement of the trunnions IS in the guides ii. A vertically disposed travel bar I! extends parallel to the guides 16 and is pivotally connected with the arms M by means of the outer ends of the trunnions IS, the inner ends of which are received in the guide 16, as above described. Due

to the connection of this travel bar with each of 5 controlled independently of the position of the one controlling sash, I connect one sash to the travel bar H by means of a shoe l8. In the drawings the shoe I8 is illustrated as connectedto the lower sash, and this ordinarily will be the case due to the fact that the lower sash is more easily accessible than the upper sashes and due to the fact that it is often desirable to closethe lower sash while the upper sashes are in an open position. It will be apparent, however, as the description proceeds, that any one of the sashes may be used as a. control sash; and it will also be apparent that the number of sashes in a window has no bearing on the application ofmy invention, which is equally well adapted to windows having any number of sashes. It is likewise immaterial whether the sashes swing inwardly or outwardly, or whether some of the sashes swing inwardly while others swing out wardly.

The details of construction .of the shoe by means of which the lower sash II is connected with the travel bar are best shown in Figs. 4 and 5; and thepositions assumed by the shoe during the several stages of operation of the control sash are illustrated in Figs. 6 to 8, inclusive.

Referring to Fig. 5, the shoe is illustrated as consisting of a body portion built up of an inverted U-shaped strip 19 secured at its ends by means of rivets 20 to 'a spreader 2|. The side walls of this body portion formed by the strip 19 are spaced apart to form a slot 22 and, if desired, the shoe may be made of a solid piece of metal having the slot 22 milled therein. A rivet 23 is shown to form a pivoted connection between the shoe and the arm H of the control sash, and the back of the shoe is slidably received in the guide I6 in the window-frame. Disposed within the slot 22 of the shoe are a latch 24 and a tumbler 25. A pivot pin 26 supports the latch for rocking movement relative to the shoe, which rocking movement is limited by a pin 21 extending between the side plates of the shoe and passing through an enlarged hole 28 in the latch. The pivot pin 26 is disposed as nearly as possible at the center of gravity of the member forming the latch so that the latch will tend to remain in whateverposition it is placed. The hole 28 cooperates with the pin 21 to permit the upper end of the latch to swing outwardly to expose an upper shoulder 29, as in'F-ig. 6, and

inwardly to conceal said shoulder and present .an inclined surface 29 i1,'- as in Fig. 7. The lower edge of the latch is provided with a lower outer shoulder 30 and a lower inner shoulder 3|, both of which shoulders project beyond the front face of the shoe in either position of the latch. A flat surface 30a occupies the space between the shoulders 30 and 3| for a purpose hereinafter to be described.

The tumbler 25 is pivotally supported on a pin resiliency of the metal of, which it is formed,

be urged toward the face of the shoe; and the extreme lower end of the travel bar is prov d with an elongated opening or slot 32 engageable with the latch 24 to form an operating connection between the control sash and the travel bar. The manner in which the control sash is connected with and released from connection with the travel bar is illustrated in Figs. 6, '7, 8

and 9, wherein the relative positions of the lower.

.to the travel bar, the other sashes, which are permanently connected therewith, will follow the movement of the control sash; whereas, if this connection is broken, the control sash may be moved independently.

Fig. 6 illustrates the normal position of the shoe and travel bar with all of the sashes in their closed position. In this view,- both the upper shoulder and the lower inner shoulder of the latch 24 are in position to be engaged with the slot 32 in the travel bar. Upon initial opening movement of the lower sash, the shoe moves downwardly, tilting the latch to the position of Fig. 7 where the upper shoulder 29 is retracted and the lower shoulder firmly engages the travel bar. Upon further opening movement the shoe draws the travel bar downwardly with it to open the other sashes connected therewith. All of the sashes are opened to the same angle, which is determined by the angle of the control sash. It may then be desired to close the control sash, leaving the other sashes in their open position. Upon closing movement of the control sash, the

During this upward movement the travel bar rides over the incline 29a of the latch 24, and the incline 34 of the tumbler 25. As the shoe moves upwardly, the pressure of the travel bar swings the latch about its pivot to project the upper shoulder again. Thus, during the closing movement of the control sash, there is no operative .shoe moves upwardly, as illustrated in Fig. 8.

connection between the latch 2| and the travel bar.

In order to close all of the sashes by manipulation of the control sash, the latter is again moved to an open position, which movement is accompanied by downward movement of the.

shoe. During this downwardmovement of the shoe, the tumbler 25 operates to insure engagement of the travel bar with the'surface 300 of the latch. As the shoe moves downwardly, the

tumbler engages the travel bar which swings the.

tumbler to the full-line position of Fig. 9. -The travel bar rides over the surface 35 and just as the control'sash is opened to the angle of the other sashes, the travel bar leaves the tumbler which causes it to come to rest on the surface 30a of the latch and in engagement with the lower outer shoulder 30. If the opening movement of thecontrol sash is continued, the other sashes will follow, due to the engagement of the travel bar with the shoulder 3ll. However, as soon as the opening movement is discontinued, the resiliency of the travel bar causes it to press inwardly on the surface 30a of the latch, which is thereby tripped to the position shown in Fig.

6 where its upper shoulder 29 will engage with the travel bar. The control sash is then closed,

movingthe shoe upwardly to impart the same sash in closed position, and to conceal the operating mechanism. a

With the mechanism above described, opening of the control sash will cause opening of all other sashes controlled thereby. The control sash may then be closed independently and will be entirely 'free of the others until it is agai opened as iar as the others,whereupon it will gain. assume its controlling relation to them. It should here be noted that even if the control sash is opened farther than the others, it will, upon subsequent closing. movement, also cause them to close. This latter feature is a decided improvement over structures in which the control sash must be moved to a certain position inorder to effect the desired engagement.

I have, for the purpose of illustration, shown my invention as applied to a window comprising three outwardly-swinging sashes and in which" the lower sash is .employedto control the others.

escontrolled by operation of one sash, means whereby opening of the control sash to any an-l I gle will cause opening of the other sashes, means operating automatically upon opening movement whereby the control sash may be independently 5 closed, and means whereby opening of the control sash to the same angle will connect it with the other sashes for further opening movement or for closing movement;

In an operating mechanism for multiplel0 sash windows comprising a travel bar and a shoe, movable longitudinally of the travel bar, means for connecting the shoe and travel bar comprising -a pivoted latch having an upper latching shoulder and a lower latching shoulder, and a 15 pivoted tumbler engageable with the travel bar to control engagement of the travel bar and latch upon their relative movement.

4. In an operating mechanism of the characte r described for multiple-sash windows, a travel bar having anopening formed therein, a shoe movable relative to the travel bar, and means for connecting the shoe and travel bar comprising a latch pivoted to' the shoe and having latching shoulders engageable'in said opening, and a tumbler pivoted to the shoe and changeable It is, however, to beunderstoodthat the inven-with the travel bar to control'engagement oi the tion is in no way limited to this particular dis-' closure, as it m'aybe used in many types 01' windows regardless of the number of sashes, the, direction that they swing, -or the particular sash 'that is chosen to control the others.

In connection with the structure of the shoe l8, it should be noted that neither the latch nor the tumbler depends upon gravity; for its operation, and it is thus possible to invert the shoe for use in certain combinations or sashes where it may be used to better advantage in an inverted position. 1 It should also be understood that variations and changes may be resorted to in the construction and arrangement of the several parts of the invention as above described, within the scope of the appended claims.
